(Cover) - EN Showbiz - The Spice Girls are said to be nearly "all on board" to do a reunion concert tour.

Victoria Beckham, Mel C, Mel B, Geri Halliwell and Emma Bunton all gave a spectacular performance during their show at the London Olympics Closing Ceremony Sunday.

The girls were so thrilled by the experience and most of them are considering joining up again for a few shows around the world.

Victoria is thought to have reservations.

"Mel B is spearheading the crusade for the band to do a reunion tour as they had a total blast performing at the Closing Ceremony. Geri Halliwell, Mel C and Emma Bunton are all on board, but, of course, the lone holdout is Victoria," a source told Radar Online.

"Vicky says she just has way too much on her plate right now with her fashion label and so busy being a mother to four young children, and wife to David and it just doesn't seem like she wants any part of a reunion tour. The ladies are ready to perform with or without Posh Spice." (C) Cover Media
